Customer Ratings & Reviews

Pick this up over a APC do to a recommendation from a friend. Very happy. Remote software uses usb and works as long as you have a pc within reach/ no network connectivity. Display is and button layouts very clean.

Only had a glitch in power since purchased, but appeared I had 119 minutes left of power.

Works great, and has already saved all my electronics from shutting down during a storm.

Only time will tell how long this thing lasts, but it's storm season in Florida and I don't want my TV, receiver, shield, ps5, etc connected to the wall without surge and battery backup. So far so good though.

I've had this for over a month now. Its worked very well and given enough power to my computer and not gone out on overload. My 850 watt UPS flipped its breaker when I started a game with serious grapics. I love the readout and the details there. It doesn't look like the anperage reflects nonlinear current, which computers are noted for. I haven't double checked it yet with a RMS amp meter. It was the nonlinear load that was tripping my old 850 watt UPS breaker. I love the plug-ins in the back. I did, however, have to use an aditional power strip for all my big blocky plugs.

We bought this for our sensitive equipment as well as some lights as our neighborhood loses power frequently. Easy to set up, used the app to mute the beeping alert and we can continue about our business for quite some time!

I highly recommend these Sine wave power conditioning power battery backup systems. I have them for my office and living room entertainment system

My main UPS was getting some age on it (5 years, I think), and when we had a power flicker the other night, it dropped like a rock. I could have replaced the batteries for about half of what a new unit would cost, but I'd still be working with a 5-year-old device. I opted to buy a new one.

I think this is the best battery backup/surge protector going. It's display is super helpful because it shows wattage used. You can't go wrong with CyberPower.

Works great! We use these at the church in out booth to maintain the integrity of our equipment during storms.

I lost electricity and it did what it was suppose to do. Glad I had it.

Works well. I had an actual outage a few days ago and It keep my critical 2 PCs, 2 routers, and switch up so that I could gracefully down my system and prevent data loss. I highly recommend this UPS.

Battery in the unit lasted less than 2 years. The UPS started alarming and I got the E21 Battery Output Short Fault code when I ran the self test. It says it has a 3yr warranty so I reached out to CyberPower support to see what they can do. Unfortunately they said I had to ship the entire unit to them at my cost (which was like $70). I asked if they could just ship me the battery so that I can replace it and they said they need the entire unit. Well I ended up buying new batteries on Amazon for less than $50 and they now work fine. In summary, the original batteries didn't even last 2 years and the warranty is not helpful. I also have an APC UPS and so far its lasting longer.....not sure how good their warranty is.

Keeps things powered and been working great for over six months without a hiccup.

We have frequent power outages and this really keeps my computer and internet running smoothly. Haven't had to test it for long periods, but when the power goes out for 10 or 15 minutes everything stays steady.

Works great so far. No issues and is not loud. Will come in handy during power hits.

clean even power, great back up unit, small enough to be used on desk

Great product for protection your Electronics Energy Last from Fifty to six to minutes

Had to get a new one after my older one died (after 5 years!). Of course I bought another CyberPower!! (It did smell for a couple days, but they all do to some extent. Some other brands smell REALLY bad for a longer time)

In my subdivision we were having weekly power surges so I bought this and it works well when the power is tripped. We’ve only had one power outage since I bought it, I’ve had for 2 months now.
